One of the recent pinnacle texts exploring the anti-geek bias, Nerds: How Dorks, Dweebs, Techies, and Trekkies Can Save America, And Why They Might Be Our Last Hope (originally released in 2007 with a 2011 reprint) is written by David Anderegg, Ph.D who comes from a child therapy background and takes the focus of his book to what he knows best; childhood.
Much of our perceptions of the world, good or bad, are formed when we are children. If we are praised or bullied about certain things, especially in a recognizable pattern over time, we're going to develop an understanding of how the world works from these experiences. An unfortunately common occurrence in schools is kids being bullied for being "nerdy". This could take shape in any number of ways, and Anderegg goes in depth to explore where this comes from in a historical context as well as a cultural one for America specifically. It is a fascinating topic to explore, especially due to the fact that America is rather unique in its bias towards geeks and nerds or a certain anti-intellectualism, as it is formally referred to in the book.
A strong point that Anderegg makes is how dangerous this bias towards geeks and nerds is for our country in terms of our collective psyche as well as our economy if we create a culture where being interested in math, science, and/or technology is constantly discouraged by bullying in our schools and negative images in our media. While strides have been made in recent years, we still have a lot of work to do to break down these stereotypes and take back the mantle of geek pride.
I highly recommend this book for anyone interested in the topic of geek culture. I read it on the recommendation of a mentor of mine in this space and was glad I took some time for it. It definitely adds some scholarly credibility to any discussion you have on the topic.
